Electrons also have charge, which gives them an extra dimension and ability to interact with electromagnetic forces, gravity and weak nuclear forces. Neutrinos do not have charge and only interact with weak nuclear and gravitational forces. These minute interactions enable them to traverse the universe at close to the speed of light virtually unmolested. The neutrino's tiny mass helps it play a crucial part in astrophysical processes of all kinds.
Can concrete be recycled?

Recycling concrete keeps large amounts of the material out of landfills. Recycling also reduces the amount of new aggregate material used, which helps protect resources. The size of the crushed concrete depends on the eventual use of the product. The recycling process involves removing any steel used for reinforcement or other items embedded in the concrete. Recycling concrete also requires attention to ensure contaminants, such as asphalt, wood or sealants, are removed.
What are some facts about the Krakatoa volcano?

Krakatoa held three volcanoes: Perboewatan, Danan and Rakata. On Aug. 26, 1883, Perboewatan erupted, spewing debris 15 miles into the air. The next day, four explosions occurred so violently that Perboewatan and Danan sank into the Sunda Strait. When water from the strait hit the magma, the water flash-boiled and resulted in flows of boiling mud that rushed down the sides of what remained of the mountains at 62 miles per hour.\nVolcanic gas suffocated many people living in western Java and Sumatra, but a 120-foot tall tsunami that resulted from the collapse of the volcanoes killed tens of thou..
Where do plants come from?

Young plants use food stored in the seed until they can create their own using photosynthesis. The seedling grows roots to help anchor it into the ground and absorb water and nutrients from the soil. The stem grows upward pushing its leaves toward sunlight at the surface, and eventually, a shoot emerges from the soil, ending the germination phase. A plant that continues to get water, warmth, light and nutrients will continue to grow.
How do marine biologists use math in their work?

Because math is the essential language of science, marine biologists use math to solve a number of complex problems in their line of work. These problems require the need for the biologists to collect and analyze data in a variety of forms. Marine biologists use the data to make theoretical models and predictions, and that information is sometimes used to establish policy changes. Sometimes marine biologists have tasks that require solutions to be prepared at a number of different concentrations, and solving those problems requires the skill of balancing equations and algebra.\nAnyone studying..
What is mercury cyanide?

Exposure to mercury cyanide produces symptoms of mercury poisoning and cyanide poisoning. If inhaled, rescue breathing must begin immediately, and nitrite pearls should be administered. Intravenous solutions of sodium nitrite can also be used to counteract the effects of mercury cyanide poisoning. Mercury cyanide poisoning affects kidneys, sensorimotor skills and breathing.\nPhysical properties of mercury cyanide include turning gray when exposed to light, dissolving 9.3 milligrams per 100 milliliters of cold water, and irritating levels of 0.02 milligrams per cubic meter of air. Acute poisoni..
How long is a human colon?

The colon has four layers of tissue, all of which help waste matter pass easily through the lower gastrointestinal tract. These tissues either secrete lubrication or are muscles that cause the colon to contract and push the material forward. After water is removed and the bacteria in the gut ferment previously unabsorbed materials, this fecal matter is stored in the rectum and passed out of the body.
Where does the energy released by fault movement form?

The tectonic plates that comprise the crust of the planet float atop a layer of molten rock, or magma. Convection currents within the magma move the plates. When they become stuck, the energy of their motion builds up along the fault. The plates move slowly but are extremely massive, so they exert tremendous forces on each other. Once the fault breaks free, all of the energy is released in a short amount of time, and the plates often move dramatically.\nThere are many different types of faults, but all store energy in the same way. One of the most destructive types of faults are found along su..
Where can you find out if there was an earthquake last night in California?

An earthquake occurs when two sides of a fault, which is a fracture of the earth's crust, move against each other. Earthquakes are common in California due to the large number of faults located throughout the state. The state typically sees two to three earthquakes of a magnitude of at least 5.5 each year, according to the California Department of Conservation. Sites such as Cal Tech's Earthquake Data Center help people in the area stay up to date on earthquake activity.

Once a customer orders a DNA test, 23andMe sends a DNA kit that helps gather and store saliva samples. The customer then sends the kit back and receives the results in six to eight weeks, as explained by 23andMe. The DNA results include ancestry composition, family tree tool, DNA relatives, maternal and paternal lineages and Neanderthal percentage. An optional feature of 23andMe can reveal unknown relatives.
